Maize, despite being thermophyllic due to its tropical origin, demonstrates high intraspecific diversity in cold-tolerance. To search for molecular mechanisms of this diversity, transcriptomic response cold was studied two inbred lines contrasting Microarray analysis followed by extensive statistical elaboration data, literature data mining, and gene ontology-based classification. The used had been bred earlier specifically determination QTLs cold-performance photosynthesis. This allowed...
Recent progress in selective breeding of maize (Zea mays L.) towards adaptation to temperate climate has allowed the production inbred lines withstanding cold springs with temperatures below 8 °C or even close 0 °C, indicating that despite its tropical origins is not inherently cold-sensitive. Here we studied acclimatory response three contrasting cold-sensitivity selected basing on multi-year routine field data. The observations were confirmed growth chamber. Under controlled conditions...
Maize is a cold-sensitive species, but selective breeding programs have recently succeeded in producing plants strikingly well adapted to the cold springs of temperate climate, showing potential for improved tolerance. The aim present study was determine whether adaptation some inbred lines spring chills due their increased true tolerance or it only represents an avoidance mechanism, which sole mode during early stages agricultural dispersal maize towards higher latitudes. By characterizing...
Abstract Background Maize cultivation has considerably expanded beyond its place of origin in Central America. The successful adaptation maize to temperate climates can be achieved by selecting genotypes that demonstrate tolerance low temperatures, especially cold springs. In maize, at the early growth stages enables sowing, a long growing season, and eventually high yields, even climates. during not been thoroughly investigated; therefore, we tested working hypothesis several distinct...
Maize is a cold-sensitive plant whose physiological reactions to sub-optimal temperatures are well understood, but their molecular foundations only beginning be deciphered. In an attempt identify key genes involved in these reactions, we surveyed several independent transcriptomic studies addressing the response of juvenile maize moderate or severe cold. Among tens thousands found change expression upon cold treatment less than 500 were reported more one study, indicating astonishing...
In maize seedlings, severe cold results in dysregulation of circadian pattern gene expression causing profound modulation transcription genes related to photosynthesis and other key biological processes. Plants live highly cyclic life their response environmental stresses must allow for underlying rhythms. To study the interplay a stress rhythmic cue we investigated transcriptomic seedlings low temperature context diurnal expression. Severe had pronounced effect on rhythm substantial...
Background Numerous biochemical and physiological parameters of living organisms follow a circadian rhythm. Although such rhythmic behavior is particularly pronounced in plants, which are strictly dependent on the daily photoperiod, data molecular aspects diurnal cycle plants scarce mostly concerns model species Arabidopsis thaliana. Here we studied leaf transcriptome seedlings maize, an important C4 crop only distantly related to A. thaliana, throughout 10 h darkness 14 light look for...
Abstract Maize is a subtropical, cold-sensitive species. However, some varieties of this species have the potential to withstand long-term low temperatures, even at seedling stage. The molecular basis phenomenon has not been determined. In chromatin-level study, we compared cold-stress reaction seedlings two maize inbred lines showing contrasting levels cold sensitivity. cold-tolerant line was selected based on field data and previous physiological transcriptomic level studies. first...
Znaczenie kukurydzy wzrasta w ostatnich latach, o czym decyduje głównie łatwość jej uprawy, wysokie plonowanie oraz wszechstronność zastosowań tego gatunku. Wiąże się to ze wzrostem areału upraw tej rośliny. Ze względu na pochodzenie, uprawa strefie klimatu umiarkowanego wiąże z uzyskaniem materiałów hodowlanych przystosowanych do szeregu czynników abiotycznych, takich jak odmienny fotoperiod, okresowe susze i niska temperatura. Molekularne podłoże adaptacji omawianych jest słabo poznane....
Dobór sztuczny towarzyszący procesowi udomowienia kukurydzy opierał się głównie na selekcjonowaniu określonych fenotypów, w efekcie czego powstały populacje osobników jakościowo różnych od dzikiego przodka. Dalsze zmiany genomach gatunków udomowionych zachodziły etapie hodowli, podczas którego z odmian lokalnych otrzymywano, bazując ich zmienności, linie wsobne (inbred lines) o pożądanych cechach. Powstało szereg hipotez mających wyjaśnić drogi ewolucji uprawnej i rozpoznać źródła jej...
